AN AID FOR THE OPTIMUM DESIGN OF ANTENNA SYSTEMS FOR VERY LOW FREQUENCIES.
Abstract
This thesis is concerned with the antenna systems used for high power radio transmitters operating at Very Low Frequencies (10-30 kHz). General problems involved in antenna systems, from the viewpoint of their equivalent electrical circuits, are discussed. The required matching networks are covered and their relative performances indicated. A brief survey of signalling methods commonly used at VLF is included, and the relation between these methods and the aerial systems is discussed. A computer program (VLFANT) has been developed for a typical VLF aerial installation which may be used in the selection of component values for optimum operation. Written in FORTRAN IV, it is for use on a high-speed digital computer. Circuit parameter values may be changed at will, and the system response using different network arrangements easily determined. With this program as a design tool proposed systems may be completely evaluated and proposed changes to operational systems easily studied. (Author)
